Category 5 Hurricane Polo Threatens Mexico With Heavy Rains And Flooding

Hurricane Polo Track and Current Intensity

Hurricane Polo intensified rapidly during the early hours of Tuesday, September 22, 2026, reaching the maximum Category 5 level on the Saffir-Simpson hurricane wind scale, according to reports from Vanguardia and the Servicio Meteorológico Nacional (SMN). The core of the storm packed maximum sustained winds of 260 kilometers per hour with violent gusts reaching up to 315 km/h. Data from the SMN and Mexico’s Comisión Nacional del Agua (Conagua) placed the center of the system roughly 355 kilometers south of Zihuatanejo, Guerrero, and about 580 kilometers south-southeast of Manzanillo, Colima. The hurricane tracked slowly toward the east at a forward speed of approximately 9 km/h. While the storm achieved Category 5 status off the Pacific coast, meteorological forecasts indicate that Polo will begin to weaken as it moves, dropping to Category 4 strength by Saturday, September 26, 2026, before potentially making landfall in Baja California Sur as a Category 2 hurricane on Monday, September 28, 2026.

Widespread Heavy Rainfall and Affected States

The influence of Hurricane Polo, operating alongside five other atmospheric systems, threatens at least 17 of Mexico’s 32 states with heavy to intense rainfall starting Saturday, September 26, 2026. The SMN warned of intense downpours ranging from 75 to 150 millimeters across Oaxaca, Chiapas, Tabasco, and Veracruz, where swollen rivers, flash floods, and landslides remain major hazards. A secondary tier of states faces very heavy rainfall between 50 and 75 millimeters, including Sonora, Chihuahua, Durango, Sinaloa, Nayarit, Jalisco, Colima, and Guerrero. Meanwhile, Baja California Sur, the State of Mexico, Puebla, Michoacán, and Campeche anticipate precipitation totals between 25 and 50 millimeters. The expansive circulation of Hurricane Polo directly reinforces rainfall totals across Baja California Sur, Sinaloa, and Nayarit.

Coastal Hazards, Wind Gusts, and Regional Warnings

Coastal communities face severe maritime hazards alongside the inland precipitation. Conagua established an active tropical storm watch stretching from Técpan de Galeana, Guerrero, to Manzanillo, Colima. Dangerous swells generated by the hurricane’s circulation will produce waves between 2.5 and 3.5 meters along the shorelines of Baja California Sur and Nayarit, alongside waves from 1.5 to 2.5 meters in Jalisco and Colima. Wind gusts along the coasts of Baja California Sur are projected to reach up to 60 km/h, while offshore zones contend with extreme gusts tied to the hurricane’s inner core. The severe weather is driven by an unusual combination of meteorological forces, including the Mexican monsoon, atmospheric instability across the northwest, inland low-pressure areas, a developing low-pressure system off the coast of Oaxaca with cyclonic potential, and a trough extending over the northern Yucatán Peninsula. Thunderstorms generated by these combined systems will feature frequent lightning strikes and potential hail across the southern Pacific region. Even with the widespread storm activity, a separate high-pressure system will maintain high temperatures with daytime maximums reaching between 35 and 40 degrees Celsius across 15 states. Conagua officials continue constant monitoring of Polo and the concurrent weather systems.
